 What are cryogenic roses?

Since ancient times people have tried to keep flowers for as long as possible. If a few years ago I put the flowers pressed in a book or just let a bouquet dry out nicely, along with the evolution of the technology there appeared more advanced methods of preserving the flowers. One of the first methods is the treatment of flowers with special substances, obtained from plants, which ensures the preservation of the flower about 6 months. Another method is the treatment of the flower with glycerin and alcohol, which ensures a lifetime of flowers between 1 and 3 years. The most recent method is lyophilization. Called improper and "cryogenation," lyophilization involves breaking petals from roses, freezing them at temperatures between -70 ° C and -80 ° C. After frosting, the petals are squeezed and the ice turns directly into the vapor by sublimation, then thaws gradually for 3 weeks. The petals are manually remanufactured, resulting in a perfect rose with a life span of up to 25 years, if you follow a few simple rules.
